HINGE.

To all whom it may concern:

Be it known that I, JOSEPH l/VRIGHT, a subject of the King of England,residing at Overton, F rodsham, in the county of Chester, England, haveinvented certain new and useful Improvements in and Relating to Hinges,of which the following is a specification.

This invention relates to hinges, and has for its object to provide ahinge whereby the movable element to which the hinge is applied, such,for instance, as a door, may be held stationary in any position, untilwilfully moved.

In the application of my invention to a door hinge, there is employed,as customary, two parts or leaves, one leaf being affixed to the door,and the other leaf affixed to the door frame, these parts being pivotedupon and held together by a suitable rod or pin which extends the fulllength of the hinge, and is disposed in the barrels or cylindersintegral with the respective leaves.

Each part of the hinge carries one member of a clutch, the engagingfaces of which are formed with rat trap teeth, proportioned according tothe application of the hinge, one member of said clutch being secured toone part of the hinge, while the other member of the clutch is disposedwithin the other part of the hinge in such manner as to be capable ofsufiicient longitudinal movement to either fully engage with, orover-run the first clutch member.

A spring is provided which normally tends to maintain the second clutchmember in engagement with the first clutch member, one end of saidspring bearing against said second clutch member, while the other end isseated against an adjustable screw.

The clutch members, spring, and adjusting screw are all disposedconcentric with the pivot pin. Normally, said clutch members are inengagement with each other, and the door is, in consequence, heldstationary, but when the door is pushed or pulled with reasonable force,the clutch members overrun, to permit the door to be moved, reenteringinto engagement under the action of the spring when the doorbecomesstationary again.

The sliding member of the clutch may be disposed on either the movableor stationary Specification of Letters Patent.

part of the hinge, as may be found most convenient. Further, the membermay be connected by means of a wire cable with a small arm on the doorhandle, so that when the handle is turned, said sliding clutch member iswithdrawn from the fixed clutch member to permit of the door beingmoved; the two clutch members reengaging when the handle is released.

The hinge, according to my invention, may, instead of taking theplace'of the usual door hinge, be employed as a check or look, in whichcase, it will be fixed to the door independently of the ordinary hinges.

Drawings illustrating this invention, applied, by way of example, to adoor, are annexed hereto, in which Figure 1 is an elevation; Fig. 2 aplan view; Fig. 3 a longitudinal section; and Fig. 4 a sectional planview, taken as on line AA, Fig. 3, of one form of door hinge.

Fig. 5 is a longitudinal section and Fig. 6

a cross section taken as on line BB, Fig. 5 of a modified construction.Fig. 7 is a longitudinal section and Fig. 8 a cross section taken as online CC, Fig. 7 of a further modified construction. Fig. 9 is a sec tionof a further modification. Figs. 10 and 11 are, respectively, elevationand plan view of the movable member of the clutch.

In'the several views like letters of reference denote like orcorresponding parts wherever they occur.

Referring now to the drawings, but first more particularly to Figs. 1 toa:a repre sents the stationary portion or leaf of the hinge providedwith the cylindrical members or barrels Z) c, and (Z represents themovable portion or leaf of the hinge provided with cylindrical member orbarrel 6 (in the constructions shown in Figs. 7 to 9 a second barrel 6is provided).

f is the pivot pin passing through barrels b 0 and e pivotallyconnecting the two parts of the hinge together.

9 is one of the clutch members referred to, which is provided with anextension 9 screwed into barrel 6 and prevented from rotation by meansof the set screw it. 2' is the second clutch member provided with lugsor extensions 2' fitting loosely within the slotted portions 0 of barrel0. j is a spring disposed around the pivot pin 7 below said slidingclutch when the door is stationary again, said teeth of clutch 2', underthe action of said spring return into engagement with the teeth ofclutch 9 until the door is wilfully moved again.

Referring now to the modifications illustrated in Figs. 5 and 6, theadjustment of spring j is effected by a screwed plug is within a recessl in which the lower end of the pivot pin f is disposed while the upperstationary clutch element is secured within barrel 6 solely by means ofthe two set pins h.

In the modification illustrated in Figs. 7 and 8, the slots provided inthe barrel 0 are at right angles to those of the hinge shown in Figs. 5and 6'and anti-friction washers m are fitted between barrels b and 0 andbar rels e and 6 o In the modification illustrated in Fig. 9, thelongitudinally movable clutch member 2' is disposed above the stationaryclutch member g, and the adjustment of the spring is effected by meansof the screwed sleeve 70.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In leaf and barrel hinges of the typeherein described, a clutch element detachably secured to a barrel; asecond clutch element in engagement with a second barrel, with freedomto move in the longitudinal plane; and a spring wholly disposed withinsaid second barrel.

'2. In leaf and barrel hinges of the type herein described, a clutchelement detachably secured to a barrel; a second clutch element inengagement with a second barrel, with freedom to move in thelongitudinal alane' a s )rin wholl dis osed within said l :3

second barrel; and means for adjusting the spring.

3. In leaf and barrel hinges of the type herein described, a clutchelement detachably secured to a barrel; a second clutch element providedwith projections; a barrel provided with recesses within which saidclutch projections are disposed; a spring wholly disposed within saidsecond mentioned barrel adapted to normally maintain said clutchelements in engagement; and means for adjusting said spring.

In testimony whereof I aflix my signature in presence of two witnesses.

JOSEPH WRIGHT.
